Answer:
y=7/4x+7
Step-by-step explanation:
Answer:
27/100
Step-by-step explanation:
27%= 0.27= 27/100 which cannot be reduced
Theory:
The standard form of set-builder notation is <span>
{ x | “x satisfies a condition” } </span>
This set-builder notation can be read as “the set
of all x such that x (satisfies the condition)”.
For example, { x | x > 0 } is
equivalent to “the set of all x such that x is greater than 0”.
Solution:
In the problem, there are 2 conditions that must
be satisfied:
<span>1st: x must be a real number</span>
In the notation, this is written as “x ε R”.
Where ε means that x is “a member of” and R means “Real number”
<span>2nd: x is greater than or equal to 1</span>
This is written as “x ≥ 1”
Answer:
Combining the 2 conditions into the set-builder
notation:
<span>
X =
{ x | x ε R and x ≥ 1 } </span>
Hello!
First of all, let's undo the parentheses.
8x+6=18
Now we subtract 6 from both sides.
8x=12
Finally, we divide both sides by 8.
x=1.5
I hope this helps!
